Issue with sitemap: null

Hi. After the plugin update, I’m getting an error when building my Gatsby page. In the configuration, I use sitemap: null

Error:

"gatsby-plugin-robots-txt" threw an error while running the onPostBuild lifecycle:

Invalid URL: null

@mdreizin Please re-open the issue. The fix wasn’t merged in 1.6.8 CI output

semantic-release didn’t generate a new version. I think it happened because PR didn’t include a commit message with the word fix.
